APPARATUS ron PACKING sTUrFING-Boxns.

The Schedule referred to in these Letters Patent and making part of thesame.

To whom it may concern Beit known that I, DAVID L. SMITH, of Montana, inthe county of Boone, and State of Iowa, have invented a new and usefulImprovement in Apparatus to Pack Pumps and all kinds of Standing-Boxes;and I do decla-re that the following is a true and accurate descriptionthereof, reference being had to the accompanying drawings, and to theletters of reference marked thereon, and being a part of lthisspecification.-

Figure l is a representation of my apparatus, showing its application topacking a stung-boit.

Figure 2 is an end view of the head, or traversingfollower.

Figure 3 is the feed-clamp.

Figure 4 shows the sleeve, with ratchet vand pawl. A

Like letters indicate like parts in each ligure.

The object of this invention is to construct an apparatus,.by means ofwhich stuthng-boxes, engines, pumps, and other similar devices, may beuniformly packed, much more compactly than by the-ordinary methods'.

The invention consists in a sleeve, to, traverso on the piston-rod, oneend of this sleeve being provided with a ratchet, and is rotated bymeans of pawl-lever.

It further consists in securing to this sleeve a curved arm, terminatingina head or traversing follower, the outer face of which is providedwith friction-rollers;

the packing; the apparatus is also provided with a feed-clamp; thearrangement and .operation of the whole being more fully hereinafterdescribed.

In the drawings'- Y A represents la sleeve, which, for convenience, ismade in two` parts, and held together, when in position, by any suitablespring or catch.l

This sleeve is intended to surround the piston-rod a when in use, and ismade in two halves, the-more easily to b e pla-ced in position.

' The sleeve is provided with a rack, b, and, by means of the pawl-leverH, receives a rotary motion.

B is an arm, curved as shown in the drawing, and, at one end, rigidlysecured to the sleeve A, while to* its opposite end is pivoted the heador traversing follower 0, which is providedwith a small wheel, D, lwhichrotates upon a bea-ringer shaft, at vright angles with' the side of thehead; it is alsoprovided with another F is a curved guide,rigidlysecured to the aun, as

nular space around' the piston-rod a in the stuffingbox d.

. G is a hand-clamp, which, when inuse, clasps the piston-roda, andrests upon the outer end of the sleeve, `for'the purpose hereinafterdescribed.V

The operation of this device is as follows:

The packing is wound around the piston, the end.

being secured, in any convenient wa in the bottom of the stuiIing-box.

The head or traversing follower is then placed in the stuing-box, andthe sleeve A placed around the piston-rod, the curve in the arm coveringthe packing wound around the piston; and the pawl-lever is then insertedin the channel or groove inthe end of the sleeve, so that said pawl willengage with the ratchetcompelled to lay in front of the wheel E, bymeans of f the curved guide, which packs it closeiy against thepiston-rod a, by reason ofits bevel or wedge-shape and diagonalrotation. The wheel D follows, and packs the whole firmly into thestufiing-box, when the apparatus may be removed.

. By means of the hand-clamp, the operator governs the feed andpressure'of the packing, according-to the power exerted upon the clampby his hand;A that is,

va heavy. pressure upon the clamp produces a heavy pressure upon thepacking, 'while a lighter pressure obtains a corresponding pressure uponsaid packing. A spring, I, which is'secured to the end of the head G,immediately in front of the wheel E, keeps'the packing smooth, andprevents it clogging said wheel, while the pivoting of the head to thearm enables the former to conform to any variableness in the thicknessof the packing.

WhatI claim as my invention, and desire to secure by4 Letters Patent,is-

The construction of an apparatus for the purpose L described, whereinthesleeve A, arm B, head or traversing follower C, wheelsD and E, guideF, and spring I, are arranged substantially as described, and operatedby the pawl-lever H and'hand-clamp G, substantially as set forth. 4
